I have a Visual FoxPro installer (exe) that I want to launch using a WiX custom action. However, I think the VFP installer is a wrapper for an MSI as I'm getting "Error 1500" which seems to denote I'm trying to run two installers at the same time.
How can I bootstrap this third party MSI from my own MSI?
I'm currently launching the VFP installer in InstallExecuteSequence. I tried to run it in InstallUiSequence, but I'm calling my own installer from a ShellExec, so it doesn't run the InstallUiSequence.
Any pointers would be much appreciated.
